| chloroplast | organelle that converts the sun's energy into energy usable by the cell |
| chlorophyll | pigment that captures the sun's energy in photosynthesis |
| stroma | thick fluid contained inside chloroplast; site of light independent reactions |
| thylakoid | disk-shaped sac in the stroma of a chloroplast; site of the light reactions |
| light reactions | Sun energy + H2O are used to make NADPH and ATP |
| Calvin cycle | plant uses CO2 and energy from NADPH and ATP to make glucose |
| wavelength | distance between adjacent waves |
| electromagnetic spectrum | types of electromagnetic energy from gamma waves to radio waves |
| pigment | chemical compound that determines a substance's color |
| photosystem | cluster of chlorophyll and other molecules in a thylakoid |
| carbon cycle | process by which carbon moves from inorganic to organic compounds and back |
| greenhouse effect | process by which atmospheric gases trap heat close to Earth's surface and prevent it from escaping into space |
| reactants in photosynthesis | sunlight; carbon dioxide; water |
| products in photosynthesis | glucose; oxygen |
| ATP | energy molecule used by the cell to run its reactions |
